cgpt: Add powerwash partition in disk layout V3
It is required to have a new partition to preserve all
rollback data.
Partitoin no# 11 is unused, so it's a great option to choose
as the new partition's location.
The name chosen as more generic such as powerwash to allow for future
improvements if we will add more data there (other than rollback ones).
The partition won't have a filesystem.
For more information about the partition proposal, see
go/rollback-partition-proposal.
